Saiyans aren't immortal

As Vegeta described it to Bulma, Saiyans don’t live any longer than humans but they have some hormone that prevents them from appearing as if they’re aging so they can fight longer.

Sound a lot like high testosterone levels to me. Hell Goku was getting erections from Bulma when he was like four years old, there’s nothing to suggest that Saiyans don’t have stupid high testosterone levels.

Goku was 11 at the beginning of Dragon Ball, and I don’t recall any erections. But, yeah, saiyans probably have stupid high testosterone levels.
